Mobility Modeling in Mobile Ad Hoc Networks with Environment-Aware

Abstract

Simulation is the most important and widely used method in the research of Mobile Ad hoc NETworks (MANET). The topology of MANET and the mobility of mobile nodes are the key factors that have an impact on the performance of protocols. However, most of the existing works are based on random movement and the fact that the network topology is highly related to the environment of MANET is overlooked. In this paper, we propose a novel Environment-Aware Mobility (EAM) model which models a more realistic movement of mobile nodes. Environment objects such as Route and Hotspot are introduced to represent the environment components which are rendered by Scalable Vector Graphics (SVG). It is considered to be a complex model with a combination of existing conventional mobility models and network environments. This paper shows that various MANET environments can be modeled based on this work. A sample environment is also simulated and the results show that the intrinsic characteristics and properties of the environments have a significant influence on the performance of MANET protocols.
